Thermal Radiation in Nanofluid Penetrable Flow Bounded with Partial Slip Condition

The present research work is to investigate, how the pulse detonation engine's (PDE) performance is affected by thermodynamic detonation factors. This analysis deals with the evaluation of PDE by using pure fuels like hydrogen, propane, and butane and a blend of hydrogen (50%) + propane (50%), butane (50%) + hydrogen (50%) and propane (50%) + butane (50%). The performance prediction model method is based on flow paths. Performance loss mechanisms, like the refilling process are recognized and enumerated. Inside flow damage, which mostly results from shock waves inside the PDE combustion tube, is a major factor in the PDE's performance degradation. The novelty of the present analysis is to observe that the Hydrogen fuel displays the maximum specific impulse of 7280 s with a detonation velocity of 2321 m/s at the value of beta 0.17. whereas, the lowest specific impulse is produced by butane with the same beta value.

“…Rusdi et al, [42] examined thermal radiation in Nanofluid penetrable flow bounded with partial slip condition, and found that increment in the suction parameter led to a decrease in the temperature profile. Besides that, the skin friction coefficient and Nusselt number increase when the suction parameter increases.…”

In many industries, the knowledge of boundary layer flow and transfer of heat over a stretching sheet is applied. Getting the desired product from these industrial processes is usually a problem. Hence, the purpose of this examination was to establish the impact of thermal radiation and magnetic dipole on the movement and conveyance of heat in Jeffery fluid over a stretching surface that is linear. The model equations of the problem are converted into coupled nonlinear ordinary differential equations employing similarity transformations. The Chebyshev spectral collocation method was utilized to get a solution for the fluid’s velocity and temperature. The different parameters in the problem are varied to determine their influence; these effects are represented by tables and graphs as determined by the prescribed surface temperature (PST) and prescribed heat flux (PHF) thermal processes. Results for particular cases are compared with those gotten by the Generic algorithm and Nelder Mead method, and a very good agreement exists. Thermal radiation causes an increment in temperature for PST and PHF processes, while magnetic dipole reduces the velocity of the fluid and increases temperature for the case of PST whereas it exhibits both an increase and decrease in temperature for the PHF case.

“…Kiran Sajjan et al, [9] explored the presence of Fourier fluxes and Boussinesq quadratic thermal oscillations, the impacts of linear, non-linear and quadratic Rosseland approximations on the behaviour of three-dimensional flows with ternary hybrid nanoparticles of various shapes and densities and Dinesh Kumar et al, [10] has done with hybrid nanofluids. Rusdi et al, [11] investigated the nanofluid penetrable flow over an exponentially diminishing sheet with heat radiation and partial slip of silver (Ag) nanoparticles in water and kerosene. Prasad et al, [12] studied the radially stretched Riga plate transfers mass and heat from an unsteady, electrically conducting and viscous nanofluid.…”

This study pitch into the three different types of hybrids nanofluids flow across a semi-infinite moving vertical plate exposed to the radiative magnetic field and are also implanted in a porous medium. The governing equations corresponding to the problem is a linear partial differential equation which are simplified by appropriate non-dimensional quantities and solved using Laplace transform technique. Exact general solutions for the dimensionless velocity and temperature, concentration fields as well as the accompanying skin friction, Nusselt number and Sherwood number are graphically derived. Increase in the parameters like permeability, Grashof number for heat and mass elevates the hybrid nanofluids velocity profile. When the magnetic parameter increases there is a retardation in the flow speed. Heat transfer rate slows down when the radiation increase. It reveals that Prandtl number lowers thermal boundary layer thickness. Intensification of chemical reaction lowering the concentration. Elevation of Schmidt number, accelerates the mass transfer. This study, also have a keen interest in determining which type of hybrid nanofluid provides the greatest enhancement in velocity and temperature.
